What are benefits of using structural box beams?
A structural box beam is a load-bearing structural member with a hollow rectangular or square cross-section. This closed-section design provides high strength and stiffness while keeping the overall weight relatively low. Structural box beams are commonly used in long-span and heavy-load applications where performance, efficiency, and durability are critical. This article will briefly introduce what are benefits of using structural box beams.

Steel structure box columns
A steel structure box column is a high-strength structural member with a hollow square or rectangular cross-section. Its box-shaped geometry improves load-bearing efficiency, bending resistance, and shear performance, while reducing overall material weight compared to solid columns. Steel box columns are widely used in modern construction, bridge engineering, and large-scale infrastructure projects that require high strength, stability, and durability.
